Schioppa’s L12 Series features a complete and diverse line of institutional casters and wheels. Within the L12 series you will find two wheel options, a precision ball bearing wheel and a plain bore wheel. Precision ball bearing wheels offer greater reliability, as a precision ball bearing is molded into the middle of the wheel. Precision ball bearing wheels make objects easier to push requiring less effort from the user. Plain bore wheels feature a standard plain bore and are designed for the cost conscious consumer. Every Schioppa L12 caster offered is features a crown tread wheel instead of the industry standard flat thread wheel. Crown tread wheels are designed to push debris away from the wheel while the caster is in operation. This makes the caster even easier to operate for the user. With numerous wheel options, custom stems, a huge assortment of colors and materials, look no further to find your perfect caster.
